GGT7 and breast carcinoma: Univariate analysis of breast cancer patients with low GGT7 expression have poor prognosis and high risk of recurrence and metastasis, and are potential breast cancer metastasis suppressor genes. Changes in the expression level of GGT7 may affect the malignant progression of tumor cells, and correlate with the clinical stage and the number of positive lymph nodes, and the detection of the expression level of GGT7 can accurately assess the prognosis of breast cancer patients, and provide an objective basis for the formulation of individualized clinical treatment plans [71].
